Discussion
----------
20060802 (Warly)
* I prefer creating a separate scheduler, so that it can eventually call
other bots.
* bots should be able to take packages by themselves.
* Iurt will perform several checks, they have to be standard and usable
by the maintainer, the results must be put in a visible directory or path
* We can put packages either in a dir or to prefix all files with the date
and uploader. Having all files in a dir will make the listing simpler.
Prefixing the files could be problematic if we base the rpm name and
version parsing on the filename.
* ulri knows the prefix, he could ask iurt to put the packages in a dir
with the same prefix.
20060806 (Warly)
* All the packages are put in done, then the final youri is run to put them
in queue/
20061104 (claudio)
* Instead if having configuration defaults for our environment and using
ulri with the defaults, it would be nicer to have minimalistic/generic
defaults and install a configuration file in kenobi
* Ulri's configuration file could be renamed to .ulri.conf instead of
.upload.conf. ==> ok, it's also used by emi
